The 1989 Buick Reatta came from a period when Buick was blending personal-luxury coupe styling with late-1980s front-wheel-drive packaging and a more modern, electronics-focused driving experience. It stands apart from larger traditional Buicks, which makes correct tire selection especially important to both appearance and road manners. The 1989 Buick Reatta uses a single primary tire size, 215/65R15, in radial construction on a 15-inch rim. Within that size, there is still meaningful choice in brands, sidewall presentation, and tire series, including raised white letter, redline, and wide whitewall options. That makes the decision less about fitment range and more about matching the car's intended look, wheel setup, and driving use.
Which Tire Size Is Right for The 1989 Buick Reatta
The 1989 Buick Reatta uses one primary tire size: 215/65R15 in radial construction on a 15-inch rim. The Base sub-model uses that same size, so the main decision is not which primary size fits, but which 215/65R15 tire best suits the car's appearance, wheel width, and intended road use.
A 215/65R15 tire uses a 215-millimeter nominal section width, a 65-series aspect ratio, radial construction, and a 15-inch rim diameter. On the 1989 Buick Reatta, that modern metric radial format matches the car's original-era fitment approach and keeps the selection centered on proper radial sizing rather than vintage bias-ply interpretation. Available choices include Goodyear, Cooper, and BFGoodrich, with sidewall treatments such as OWL, RWL, redline, and wide whitewall across series like Eagle GT, Cobra Radial G/T, Silvertown Radial, and Radial T/A. It is the right starting point when the goal is correct size fitment with room to tailor the car's visual character.
Sub-model fitment is straightforward for the 1989 Buick Reatta. The covered Reatta sub-model uses the same primary tire size, so the focus stays on choosing the right 215/65R15 radial rather than sorting through multiple fitment combinations.

Tire Size & Fitment
What tire size fits a 1989 Buick Reatta?
The 1989 Buick Reatta uses a 215/65R15 radial tire. That is the primary fitment for the model and it pairs with a 15-inch rim, making it a straightforward modern metric radial size rather than an older bias-ply or alphanumeric format.
The practical next step is confirming that the car still has the correct 15-inch wheel setup and a wheel width that suits the tire being considered. Once that is confirmed, the decision usually comes down to sidewall style, brand, and tire series, since several 215/65R15 radial choices are available for different visual preferences.
What size rim does a 1989 Buick Reatta use?
The 1989 Buick Reatta uses a 15-inch rim with its 215/65R15 tire size. That rim diameter is built into the size itself, and the available tires in this fitment are designed around 15-inch wheel use.
Rim diameter is only one part of the fitment check, so wheel width still matters when comparing actual tire options. Some 215/65R15 products are built around a 6-inch wheel, while others allow a wider range, which is worth verifying if the car has replacement wheels or if the original setup has been changed.
Does the 1989 Buick Reatta Base use the same tire size?
Yes. The 1989 Buick Reatta Base uses the same 215/65R15 radial tire size as the covered Reatta fitment. That keeps the fitment picture simple and avoids the confusion that can come with trim-specific size changes on some other vehicles.
Even with shared sizing, tire selection can still vary in appearance and specification. A Reatta owner can choose among raised white letter, outlined white letter, redline, or wide whitewall presentations, so once size is confirmed, the remaining decision is how closely the tire should match the car's intended period look and road use.
Choosing the Right Tire
What should I consider when choosing a 215/65R15 tire for a 1989 Buick Reatta?
Start with the correct primary size, 215/65R15, and verify that the tire matches the car's 15-inch wheel setup. From there, compare construction, rim-width compatibility, sidewall style, tire series, and load figures such as 1510 lbs. @ 35 psi where those details are shown.
The right choice depends on what matters most for the car. A Reatta kept close to its late-1980s personality may lean toward a sporty raised white letter look, while a more distinctive show-oriented presentation might favor redline or wide whitewall styling. Wheel width and the car's actual use should guide the final comparison.
What sidewall styles are available for 1989 Buick Reatta tires?
The 1989 Buick Reatta's 215/65R15 tire choices include OWL, RWL, redline, and wide whitewall sidewall styles. That gives the car a broad visual range, from a more performance-oriented late-1980s appearance to a softer, more customized or touring-inspired presentation.
Sidewall style changes the look of the car more than the fitment itself, so the best choice depends on the Reatta's overall finish and purpose. A stock-looking driver may suit one presentation, while a more personalized car may suit another, but the tire still needs to be evaluated for wheel-width compatibility and general condition before use.
What brands offer tires for the 1989 Buick Reatta?
Goodyear, Cooper, and BFGoodrich all offer 215/65R15 radial tires for the 1989 Buick Reatta. The available series include Eagle GT, Cobra Radial G/T, Silvertown Radial, and Radial T/A, giving the car several distinct tire personalities within the correct size.
Brand choice should be treated as part of a larger comparison rather than the only deciding factor. Looking at sidewall treatment, rim-width range, tire series character, and how the tire complements the Reatta's style will usually tell the buyer more than the brand name alone when several correct-size options are on the table.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Buick Reatta?
A period-style 1989 Buick Reatta should start with the correct 215/65R15 radial size, then narrow the choice by overall appearance. Raised white letter and outlined white letter options lean into a late-1980s sporty look, while redline or wide whitewall choices create a more specialized visual statement.
Because appearance goals vary from preservation to personalization, the right tire depends on how the car is being presented. Owners pursuing exact originality should compare the car against authoritative Buick literature, window sticker information, or marque references, while also checking that the selected tire's rim-width requirements match the actual wheel on the car.
Does correct tire fitment matter for a 1989 Buick Reatta restoration?
Yes, correct tire fitment matters on a 1989 Buick Reatta restoration because tire size and sidewall presentation have a strong effect on stance, visual balance, and how authentically the car reads. Staying with the proper 215/65R15 radial size keeps the restoration grounded in the right fitment starting point.
Appearance is only part of the equation, since the tire also has to suit the wheel and the way the car will be driven. Even on a lightly used collector car, it is smart to confirm wheel size, check for suspension changes, and avoid assuming that any 15-inch tire with a similar look will preserve the intended proportions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Buick Reatta?
Yes, modifications can affect tire fitment on a 1989 Buick Reatta even when the intended tire size remains 215/65R15. Changes such as aftermarket wheels, altered wheel width, suspension work, ride-height changes, or body modifications can all influence how much room the tire has in normal driving and steering movement.
A Reatta that no longer has its original wheel and suspension setup should be checked carefully before a new set of tires is chosen. Verifying actual wheel width, confirming 15-inch rim diameter, and checking clearance at the fender, inner wheelhouse, and steering range will help prevent fitment surprises after installation.
What should I inspect before driving a 1989 Buick Reatta on new tires?
Before driving a 1989 Buick Reatta on new tires, inspect the wheels for damage, confirm proper tire pressure, and make sure the tires seat correctly on the rims. It is also wise to check for suspension wear, alignment issues, and any signs that the car has unusual clearance concerns from prior modifications.
A short initial road test can reveal vibration, rubbing, pull, or steering issues before the car is used more seriously. After that first drive, recheck inflation, look over the sidewalls and tread, and make sure there is no contact under turning or compression, especially if the car has spent long periods in storage.
How should 215/65R15 tires on a collector 1989 Buick Reatta be maintained?
Collector-car maintenance for 215/65R15 tires on a 1989 Buick Reatta starts with regular pressure checks, periodic visual inspection, and attention to age-related deterioration. Even a lightly driven car can develop cracking, flat spotting, air loss, or sidewall damage if it sits for long stretches without proper storage and monitoring.
Keeping the car away from prolonged sunlight, moisture, and ozone sources helps preserve the tires between drives. It also helps to move the car occasionally, inspect tread and sidewalls before road use, and avoid treating low mileage alone as proof that an older tire is still ready for dependable service.
